NVIDIA has introduced Alpamayo 2 Super, a powerful 34-billion-parameter Vision-Language-Action (VLA) model designed to advance autonomous driving and robotaxi technology. Released under the OpenMDW-1.1 commercial license, the model combines cutting-edge AI reasoning, vision understanding, and driving action planning into a single framework that developers and enterprises can deploy commercially from day one.
Unlike conventional autonomous driving systems that rely on multiple perception, prediction, and planning modules, Alpamayo 2 Super integrates these capabilities into one unified model. It is specifically engineered to handle long-tail driving scenarios—rare and highly complex situations involving multiple road users that often challenge traditional autonomous driving systems.
With open model weights, Apache 2.0 source code, large-scale training data, and industry-leading benchmark performance, NVIDIA aims to provide researchers, automotive manufacturers, and AI developers with a scalable foundation for the next generation of intelligent driving systems.
A Unified AI Model for Complex Driving Decisions
At the core of Alpamayo 2 Super is a 32B Vision-Language Model (VLM) built on NVIDIA Cosmos 3 Super Reasoner. The backbone has been further enhanced using reinforcement learning, allowing the model to improve its reasoning capabilities during autonomous driving tasks.
Complementing this backbone is a 2.3B diffusion-based action decoder, which converts visual understanding and reasoning into driving actions. Together, these components create a complete 34B Vision-Language-Action model capable of analyzing driving environments and generating driving plans in a single forward pass.
Rather than processing separate perception and planning pipelines, the model simultaneously interprets camera feeds, understands road situations, reasons about surrounding traffic, and predicts vehicle actions. This integrated architecture reduces system complexity while improving consistency between perception and planning.
Designed for Long-Tail Driving Scenarios
One of the primary goals of Alpamayo 2 Super is addressing long-tail events in autonomous driving.
Long-tail scenarios are uncommon yet safety-critical situations that occur infrequently in real-world traffic. These may include unpredictable pedestrian behavior, unusual vehicle interactions, temporary road changes, or complex multi-agent environments.
Traditional autonomous driving stacks often struggle with these edge cases because perception, prediction, and planning operate independently. NVIDIA’s Vision-Language-Action architecture instead reasons about the entire scene before selecting an action.
The result is a system capable of producing not only a planned driving trajectory but also an explanation describing why the chosen action is appropriate.
Open Commercial License Supports Immediate Deployment
One of the biggest advantages of Alpamayo 2 Super is its licensing model.
NVIDIA has released the model weights under the OpenMDW-1.1 license, developed by the Linux Foundation for open model distribution. The accompanying source code is licensed under Apache 2.0, giving developers significant freedom to build commercial applications.
The licensing allows organizations to:
- Fine-tune the model
- Build derivative AI models
- Deploy commercially
- Redistribute trained versions
- Integrate into proprietary software
Importantly, NVIDIA has extended the OpenMDW licensing approach across the entire Alpamayo family, meaning previously research-focused releases can now be used commercially without requiring additional permissions.
This makes Alpamayo 2 Super attractive for automotive manufacturers, robotics companies, and AI startups seeking an enterprise-ready autonomous driving foundation.
Input Data and Model Outputs
Alpamayo 2 Super is designed to process multiple forms of driving information simultaneously.
The model accepts:
- Multi-camera RGB video
- Text prompts
- Timestamp information
- Multi-step egomotion history
The validated public notebook uses six surround-view cameras, with four historical frames per camera to provide temporal context.
Vehicle movement is represented using 3D translation together with a 3×3 rotation matrix across multiple timestamps.
After analyzing the environment, the model generates a driving trajectory consisting of 64 waypoints covering 0.1 seconds to 6.4 seconds, spaced at 0.1-second intervals.
Each waypoint includes:
- Ego-frame XYZ coordinates
- 3×3 rotation matrix
This trajectory provides detailed planning information for autonomous driving systems.
Massive Training Dataset Improves Generalization
To improve robustness across diverse driving environments, NVIDIA trained Alpamayo 2 Super using an extensive autonomous driving dataset.
According to NVIDIA, the model learned from approximately:
- 115,000 hours of multi-camera driving video
- Egomotion records
- Vehicle trajectory annotations
- Around 3.7 million Chain-of-Causation (CoC) traces
- More than one billion training images
Chain-of-Causation traces represent structured explanations that describe why the AI selected a particular driving action.
Instead of simply predicting steering or acceleration, the model learns causal relationships between road observations and driving decisions.
This additional supervision improves interpretability while supporting AI safety and validation workflows.
Strong Benchmark Performance
NVIDIA reports impressive benchmark results across language understanding and autonomous driving evaluations.
On LingoQA, Alpamayo 2 Super achieved a Lingo-Judge score of 79.2, ranking first among nearly 40 evaluated models.
The model also outperformed several well-known AI systems:
- Qwen2.5-VL 72B by 17.0 points
- Gemini 2.5 Pro by 15.1 points
- GPT-4o by 23.2 points
Beyond language evaluation, the model demonstrated strong planning performance.
Closed-loop testing using AlpaSim across 910 driving scenarios from the PhysicalAI-AV-NuRec dataset produced an AlpaSim score of 1.50 ± 0.13.
Open-loop evaluation using 937 challenging samples from the PhysicalAI-AV dataset achieved a minADE₆ score of 0.911 meters at 6.4 seconds, indicating accurate trajectory prediction over extended planning horizons.
These benchmark results suggest Alpamayo 2 Super performs competitively across both reasoning and autonomous driving tasks.
Five Outputs From a Single AI Model
Unlike conventional autonomous driving systems that generate only planned trajectories, Alpamayo 2 Super produces multiple outputs simultaneously.
For every driving scenario, the model generates:
- Planned driving trajectory
- Chain-of-Causation (CoC) explanation
- Meta-action such as lane change or yield
- Reasoning auto-labels
- Visual Question Answering (VQA) with 2D grounding
This combination enables developers to understand both what the model decided and why it made that decision.
Such transparency is becoming increasingly important as autonomous driving systems move toward commercial deployment.
Supporting AI Safety and Faster Data Annotation
NVIDIA states that Chain-of-Causation traces integrate with NVIDIA Halos safety validation workflows and support AI safety practices aligned with ISO/PAS 8800.
The model can also function as an intelligent auto-labeling system for proprietary fleet data.
According to NVIDIA, using Alpamayo 2 Super for annotation can reduce labeling cycles from months to just days, significantly accelerating autonomous driving development while lowering annotation costs.
This capability is especially valuable for organizations continuously collecting driving data from production vehicles.
Cloud Deployment and Future In-Car Inference
NVIDIA evaluated Alpamayo 2 Super using a single NVIDIA H100 80GB GPU, where the model reached a peak memory usage of approximately 72,115 MiB.
While the full model is designed for cloud-scale deployment, NVIDIA suggests developers can create distilled versions optimized for in-vehicle inference.
This approach enables large foundation models to support autonomous driving development while allowing lightweight variants to operate directly inside production vehicles.
Conclusion
